John Frieda ULTRAfiller+ Thickening Spray, Thickening & Strengthening Spray for Damaged or Thin Hair, Infused with Biotin and Hyaluronic Acid to Strengthen Hair for Thicker Fuller Results, 5 Oz

I think this works quite well. I do not have prior product knowledge to compare this too, have noticed some say it doesn’t work as well & has a funky smell but I think it works fine. It also smells good too. Maybe some got an old outdated batch or possibly theirs had been stored improperly in high heat? I’m a former stylist so I have used my fair share of products over the years. I’ve gotten used long ago to using different products for different things, like this product for example provides a decent thickening effect but not much hold so I use a spray gel, mousse or something w/hold with it. I also use a leave in conditioner as I have curly semi frizzy hair that is not super thick. I think the additional products also help add texture to my hair. As with everything it will react differently on everyone so try to base your decisions of reviews from people who have hair like yours. I would say this would be a good product for anyone with thin hair regardless if it is straight or curly & the diameter of each piece of hair is fine to regular.

This stuff really works. I was skeptical because I have used so many other products that did not do much for my fine, thin hair. I love this and just ordered 2 more bottles. It created volume at the top and crown of my hair. I actually amazed at the difference it made. My hair is also less frizzy. It is soft and not sticky. I'm going to tell my hair stylist about this wonderful product. If you have been considering trying it, don't hesitate. You will love it.

I have very thin and fine hair. This product makes my hair look fuller and thicker. I love it.

Huele muy rico lo cual favorece a mi pelo porque retiene mucho los olores, pero le doy 3 estrellas porque have que mi pelo retenga mas agua de la que normalmente retiene por lo que me hizo tardar mas de lo normal en secarme el pelo. Si tienes ese problema como yo pero tienes paciencia, lo recomiendo porque huele muy rico y el olor permanece en el pelo y al retener mas humedad si hace que el pelo se vea mas voluminoso

Works well, scent is pleasant,and very effective.

I washed my hair yesterday and it’s still clean this morning . The top however was soft and flat. I wet just the top to try this product for the first time. I didn’t have much hope to be honest aa my hair is thinning and fine and hadn’t been freshly washed though clean.Let me tell you!! Buy this! My hair looked so thick on top and wasn’t sticky or gunky or dry! My hair curled great with the flat iron and I pulled the back up. It looks like I just shampooed my hair and fixed it and ita got the full was I want!I’m so happy that I found this product.It’s lightweight and the scent is light and clean. My hair feels amazing and looks great. This will be my go to from now on. No more mousse. I wish the bottle was a little bigger for the price but it works and I’m worth it.

The hairs at the front of my head have thinned due to aging as well as continually pulling my hair back. Also I put my reading glasses on the top of my head all the time so those hairs can break when I reach for my glasses.I got bangs recently to try and help and then I wanted to try this product on my bangs to see if it would make them look thicker.I tried a few times and this product did NOT make the individual hair strands look any thicker. The only things it did were to make the follicles on the hairs sit down a little more (although many other products do this better) and it made the hairs get slightly stiff and stick to each other so they appeared a little thicker (a much cheaper product from any drug store can accomplish this exact same result). So as far as a thickener I am giving this 1 star. Maybe it works for heat protection but that is not what I bought it for. I tried to return the item but it was not allowed - annoying!

Works well and doesn’t leave hair the hair feeling stiff.
